我正在尝试将 XPagesJDBC.nsf 连接到一个简单的 MS Access 数据库，它成功连接并且我能够执行 @JdbcInsert、更新、删除。还能够执行 SQL 查询操作。
但是我在尝试使用 JDBC Query 数据源类型在 ViewPanel 控件中显示数据时遇到了问题。
它给出以下错误
Error while reading the relational data
Invalid Fetch Size
还有一个很长的 StackTrace，我正在复制下面的堆栈跟踪的一部分；
我认为这个错误是特定于 MS Access 的，因为我可以在其他 RDBMS 中找到一些成功的实现，它也可以在我的末尾使用“durby”正常工作。
